So I just set up my dual monitor display on my new rig running Vista 32 bit, and my right, extended monitor goes out. When I turn it off and back on it starts up, stays lit for like 20 seconds then goes black again. They green light stays lit. I had a funny power cable connected to it, so I decided to swap for a known good cable. Still giving me the problem...

Well, they're both set to 75...we have the same models at work and they're set at 75 and we never have problems. We also have worse video cards than I have in my rig...I swapped monitors and confirmed that it is the monitor because I switched it from DVI to VGA and also switched power cable and it still does it. I changed resolutions and messed with refresh rate and it continued to do it.
